A Model Based Approach For Regression Testing Utilizing Distributed Architecture

The explosive growths in the usage of object oriented programming in the development of large applications have put extensive pressure in testing and maintenance of these systems. A graphical representation for these programs has the advantage of lending to efficient analysis compared to code based textual analysis. The Class Dependence Graph (ClDG) is insufficient to capture the features of real time safety critical object oriented program. We extend the basic ClDG to incorporate features like control flow and exception handling, timing, criticality, method sequences and sate information. The model that we have developed can easily be subjected to automated analysis for establishing points within a program that needs to be tested when the program is subjected to changes.
